This event CreateDesignerObject is triggered when the user creates a new object. If desired, you can show the initial dialog to the user. This can, for instance, be an assistant that makes it simple for the user to configure the new object. If you don.t want to offer this, simply forego processing of the event. The following example show the display of a MessageBox as soon as the new object is placed in the workspace for the first time. You gain access to the designer window through the event argument. The passed class supports the IWin32Window interface and can, as a result, be used for a MessageBox or another window as a parent.
